Maybe sadly, but I play GTA for "the moments," like when you parachute off a building and land in a friend's car or you're about to take a shotgun in the face and a friend opens fire on the dude with a minigun sending him flying 20'. To date, though, my favorite moment is standing on the balcony of the motel in Sandy Creek getting ready to blast someone in one of the rooms when another player lowers an Annihilator and rains down bullets on the entire structure. Between the audio and physical feedback it was a hell of an adrenaline rush. I just stood there and fuuuuuuuuuuuuu til it stopped.
On the subject of those moments, I really enjoy that mission Denial of Service because it's utterly braindead but affords an awesome opportunity to hoon around town in the Dominator. A while back I ended up in a game with a bunch of very low-level players that had no cars, and one of them hopped in the passenger seat, waving a sticky bomb out the window. I was pretty sure my car was toast, but the guy totally proved himself. At the last truck stage, I spotted it ahead crossing of the larger intersections and I did a totally sweet power slide (well, as good as GTA will accommodate) across the intersection ending up right next to the delivery truck. Guy literally places the bomb on the side of the truck, I light 'em up and put some distance and BOOM in the rearview. Flip a bitch, park next to the smoldering remains, and the passenger grabs the equipment. So cinematic.
To me, it's worth playing just for things like that. Every so often the girl will be reading on the couch while I'm playing and she happened to catch that moment. "That was cool" she told me. Yeah it was.
